The initial fee of $12 would be the y-intercept because no matter how many boxes of cards you buy, the fee stays the same. The slope would be $3.99 because that fee is charged per box. The 100 cards per box is extra information and not needed in the equation. D is the only logical choice.

Kay [80]

Answer:Thus, (-3)-4 = 1/(-3)4.

Step-by-step explanation:

Negative exponents have the following property: n-m = 1/nm OR 1/n-m = nm

So for (-3)-4 , n= -3 and -m= -4 (or m= 4).

Thus, (-3)-4 = 1/(-3)4.

olga_2 [115]

Answer:

$576.80

Step-by-step explanation:

We have been given that Mr. Juárez opened a savings account with an initial deposit of $560 and will not make any additional deposits or withdrawals. The account earns 1% simple interest.

We are asked to find the total amount that Mr. Juárez will have in his account at the end of 3 years.

We will use simple interest formula to solve our given problem.

$A=P (1+rt)$

A = Final amount after t years,

P = Principal amount,

r = Annual interest rate in decimal form,

t = Time in years.

Let us convert 1% into decimal form,

1%=1/100=0.01

P=$560 and t=3

A=$560 (1+0.01(3))

A=$560 (1+0.03)

A= $560 (1.03)

A= $576.80

Therefore, Mr. Juárez will have $576. 80 in his account at the end of 3 years. Hope this helps!
